Description
- Embodiments of the present invention relate to an image display apparatus.
- There is a conventional image display apparatus that displays an image which appears to be differently depending on the direction a person sees the image, so that the image appears to be stereoscopic, and for example, in order to display parallax images which are shown in multiple directions and which can be seen in multiple directions, a composite image obtained by composing parallax images is recorded onto a recording medium such as a sheet by means of printing, and the image is displayed through a lenticular lens. The composite image is made by arranging multiple parallax images in a rectangular form, and the same parallax image is displayed in the same direction by many cylindrical lenses constituting the lenticular lens.
- In this case, when the position of the composite image printed on the recording medium does not match the position of the lenticular lens, the image displayed is corrupted in a conventional image display apparatus. In the conventional image display apparatus, the positional deviation includes horizontal positional deviation and inclination deviation, but it is difficult to independently adjust both of them, and it has not been easy to adjust the positions.

- First, overview of the image display apparatus of the first embodiment will be explained with reference to
FIG. 1 .FIG. 1 is a configuration diagram illustrating the image display apparatus according to the first embodiment. - As shown in
FIG. 1 , arecording medium 1 is formed with a recordedimage 2, and, for example, therecording medium 1 is attached to amedium attachment unit 3 which is a flat plate. Alenticular lens unit 4 is attached so that it is in contact with therecording medium 1 attached to themedium attachment unit 3. - The image display apparatus according to the first embodiment before and after the assembly will be explained with reference to
FIG. 2 .FIG. 2 is a transverse sectional view illustrating the image display apparatus according to the first embodiment. -
FIG. 2( a) schematically illustrates the image display apparatus according to the first embodiment before the assembly, and as shown inFIG. 2( a), therecording medium 1 is formed with the recordedimage 2, and therecording medium 1 is attached to themedium attachment unit 3, and thereafter, thelenticular lens unit 4 is attached to therecording medium 1. - Therefore, while a
lenticular lens 5 is brought into contact with the recordedimage 2, a position adjustment mechanism 6 is adjusted. In this case, thelenticular lens 5 is configured in such a manner that many inverted U-shapedcylindrical lenses 14 are arranged side by side. InFIGS. 2( a), 2(b), the vertical direction of the drawings is a direction substantially in parallel with the border lines between thecylindrical lenses 14, like the subsequent drawings. InFIGS. 2( a), 2(b), the horizontal direction of the drawings is a direction substantially perpendicular to the border lines between thecylindrical lenses 14, like the subsequent drawings - The position of the
recording medium 1 is somewhat determined by amedium abutment surface 7, but antislip processing is applied to the medium attachment surface of themedium attachment unit 3, or a antislip sheet is pasted to the medium attachment surface of themedium attachment unit 3, whereby it is made into anantislip surface 8, so that therecording medium 1 does not move together with thelenticular lens 5 when thelenticular lens 5 moves on therecording medium 1. -
FIG. 2( b) schematically illustrates the image display apparatus according to the first embodiment after the assembly, and as shown inFIG. 2( b), themedium attachment unit 3 and thelenticular lens unit 4 are fixed with screws or hooks, not shown, so as to maintain such state as to press thelenticular lens 5 and the recordedimage 2 having been adjusted. - In this case, the
lenticular lens unit 4 has the position adjustment mechanism 6.FIG. 3 is a longitudinal sectional view illustrating a lenticular lens unit of the image display apparatus according to the first embodiment. - As shown in
FIG. 3 , thelenticular lens 5 is connected via arotation center screw 11 with aslide mechanism 10 provided at an upper portion ofFIG. 3 with respect to aframe 9. - In this case, horizontal adjustment knobs 12 (hereinafter referred to as a horizontal adjustment unit) are provided to connect with the
slide mechanism 10, and for example, in a case where theslide mechanism 10 is of a direct-acting method, a user grabs one of or both of the knobs and moves the knobs in a horizontal direction (which will hereinafter refer to a direction substantially perpendicular to the border lines of thecylindrical lens 14 constituting the lenticular lens 5), so that theslide mechanism 10 connected with thelenticular lens 5 can be adjusted in the horizontal direction ofFIG. 3 . In a case where theslide mechanism 10 is of a feed screw method, a user rotates one of or both of the knobs, so that theslide mechanism 10 connected with thelenticular lens 5 can be adjusted in the horizontal direction ofFIG. 3 . In a case where the horizontal adjustment knobs 12 are of a screw method, the position in the horizontal direction is less likely to deviate from the adjusted state because of the friction of the screw even if the user releases his or her hand from the horizontal adjustment knobs 12 after the adjustment. - Further, inclination adjustment knobs 13 (which will be hereinafter also referred to as an inclination adjustment unit) are provided to be in contact with a component connected with the
rotation center screw 11 of theslide mechanism 10, and for example, in a case where the inclination adjustment knobs 13 are a direct-acting method, a user grabs one of or both of the knobs of the inclination adjustment knobs 13 at the right and the left and moves the knobs in the vertical direction (which will hereinafter refer to a direction substantially in parallel with the border lines of thecylindrical lens 14 constituting the lenticular lens), and pushes or pulls the contact portions at the right and the left of the inclination adjustment knobs 13, so that the user can adjust the inclination of the component connected with therotation center screw 11 of theslide mechanism 10 connected with thelenticular lens 5 with respect to therotation center screw 11 serving as the center of rotation. In a case where the inclination adjustment knobs 13 are of a feed screw method, a user rotates one of or both of the knobs of the inclination adjustment knobs 13, and pushes or pulls the contact portions at the right and the left of the inclination adjustment knobs 13, so that the user can adjust the inclination of the component connected with therotation center screw 11 of theslide mechanism 10 connected with thelenticular lens 5 with respect to therotation center screw 11 serving as the center of rotation. When the inclination adjustment knobs 13 are of a screw method, the inclination is less likely to deviate from the adjusted state because of the friction of the screw even if the user releases his or her hand from the inclination adjustment knobs 13 after the adjustment. - In this case, the position adjustment mechanism 6 of the image display apparatus according to the first embodiment refers to the horizontal adjustment knobs 12 and the inclination adjustment knobs 13.
- Therefore, in the image display apparatus according to the first embodiment, when the horizontal adjustment knobs 12 and the inclination adjustment knobs 13 are adjusted, the
lenticular lens 5 can be independently adjusted in the horizontal direction and in the inclination direction ofFIG. 3 with respect to theframe 9. Since the horizontal adjustment knobs 12 and the inclination adjustment knob 13 are arranged in proximity to each other, the horizontal adjustment knobs 12 and the inclination adjustment knobs 13 can be easily adjusted at a time. - On the other hand, the recorded
image 2 is formed by printing of a print apparatus.FIGS. 4( a) to 4(c) are figures illustrating a method for forming a recording medium of the image display apparatus according to the first embodiment. - As shown in
FIG. 4( a), for example, while arecording medium 22 which is a recording sheet such as paper is conveyed in a conveyingdirection 23 in a printermain body 21, and a print apparatus uses a printer head 24 to print the recordedimage 25 of a composite image made by composing multiple images parallaxes. As shown inFIG. 4( b), the recordedimage 25 is formed on the printedrecording medium 22. - Further, as shown in
FIG. 4( c), thisrecording medium 22 is attached to amedium attachment unit 26. In this case, as an indication of the position where therecording medium 22 is attached to themedium attachment unit 26, a medium abutment surfaces 27 are provided on three sides of four external peripheral sides of themedium attachment unit 26, and the external periphery of therecording medium 22 is brought into abutment with the medium abutment surfaces 27, so that therecording medium 22 can be easily positioned with respect to themedium attachment unit 26. - Subsequently, a method for producing the image display apparatus according to the first embodiment will be explained with reference to
FIGS. 5 , 6.FIG. 5 is a first flowchart illustrating a method for assembling the image display apparatus according to the first embodiment.FIG. 6 is a second flowchart illustrating a method for assembling the image display apparatus according to the first embodiment. - In this case, as shown in
FIG. 5 , first, the recorded image is printed on the recording medium 22 (step S1). Subsequently, therecording medium 22 having the recordedimage 25 printed thereon is attached to the medium attachment unit 26 (step S2). Further, thelenticular lens unit 4 is attached to themedium attachment unit 26 attached to the recording medium 22 (step S3). While a user sees the recordedimage 2 through thelenticular lens 5, the user adjusts the inclination adjustment knobs 13 of the position adjustment mechanism 6 of the lenticular lens unit 5 (step S4). - In this case, if the inclination of the recorded
image 2 seen through thelenticular lens 5 is correct (YES in step S5), the user adjusts thehorizontal adjustment knobs 12 of the position adjustment mechanism 6 of thelenticular lens unit 4 while the user sees the recordedimage 2 through the lenticular lens 5 (step S6). If the inclination of the recordedimage 2 seen through thelenticular lens 5 is not correct (NO in step S5), step S4 is performed again so that the user adjust the inclination adjustment knobs 13 again. - Further, if the horizontal position of the recorded
image 2 seen through thelenticular lens 5 is correct (YES in step S7), the processing is terminated. When the horizontal position of the recordedimage 2 seen through thelenticular lens 5 is not correct (NO in step S7), step S6 is performed again, and the user adjusts the horizontal adjustment knobs 12 again. -
FIG. 5 shows the procedure for adjusting the inclination adjustment knobs 13 first then adjusting the horizontal adjustment knobs 12, but the embodiment is not limited to this procedure. For example, in the procedure, the horizontal adjustment knobs 12 may be adjusted first, and then the inclination adjustment knob 13 may be adjusted. - As shown in
FIG. 6 , first, the recordedimage 25 is printed on the recording medium 22 (step S11). Subsequently, therecording medium 22 having the recordedimage 25 printed thereon is attached to the medium attachment unit 26 (step S21). Further, thelenticular lens unit 4 is attached to themedium attachment unit 26 attached to the recording medium 22 (step S13). While the user sees the recordedimage 2 through thelenticular lens 5, the user adjusts the inclination adjustment knobs 13 of the position adjustment mechanism 6 of the lenticular lens unit 5 (step S14). - In this case, if the inclination of the recorded
image 2 seen through thelenticular lens 5 is correct (YES in step S15), the user adjusts the horizontal adjustment knobs 12 of the position adjustment mechanism 6 of thelenticular lens unit 4 while the user sees the recordedimage 2 through the lenticular lens 5 (step S16). - Further, if the horizontal position of the recorded
image 2 seen through thelenticular lens 5 is correct (YES in step S17), the user checks whether the inclination of the recordedimage 2 through thelenticular lens 5 is correct or not (step S18). - If the horizontal position of the recorded
image 2 seen through thelenticular lens 5 is not correct (NO in step S17), step S16 is performed again, and the user adjusts the horizontal adjustment knobs 12 again. - In this case, if the inclination of the recorded
image 2 seen through thelenticular lens 5 is correct (YES in step S18), the processing is terminated. - If the inclination of the recorded
image 2 seen through thelenticular lens 5 is not correct (NO in step S18), this means that the inclination in the recordedimage 2 is deviated, which was once correctly adjusted while the horizontal adjustment knobs 12 were adjusted, and therefore, step S14 is performed again, and the inclination adjustment knobs 13 are adjusted again and the horizontal adjustment knobs 12 are adjusted again (step S14 to step S18). - Therefore, according to the flowchart of
FIG. 6 , whether the inclination adjustment knobs 13 are correct or not is checked again, and therefore, more accurately positioned adjustment state can be attained as compared with the flowchart ofFIG. 5 . - Like
FIG. 5 ,FIG. 6 shows the procedure for adjusting the inclination adjustment knobs 13 first and the adjusting the horizontal adjustment knobs 12, but the procedure is not limited thereto.

Thelenticular lens 5 is configured in such a manner that many inverted U-shapedcylindrical lenses 14 are arranged side by side. Further, horizontal adjustment knobs 12 are provided to connect with theslide mechanism 10, and for example, in a case where theslide mechanism 10 is of a direct-acting method, a user grabs one of or both of the horizontal adjustment knobs 12 and moves the knobs in a horizontal direction, so that theslide mechanism 10 connected with thelenticular lens 5 can be adjusted in the horizontal direction ofFIG. 7 . In a case where theslide mechanism 10 is of a feed screw method, a user rotates one of or both of the horizontal adjustment knobs 12, so that theslide mechanism 10 connected with thelenticular lens 5 can be adjusted in the horizontal direction ofFIG. 7 . In a case where the horizontal adjustment knobs 12 are of a screw method, the position in the horizontal direction is less likely to deviate from the adjusted state because of the friction of the screw even if the user releases his or her hand from the horizontal adjustment knobs 12 after the adjustment of the horizontal adjustment knobs 12. - Further, inclination adjustment knobs 13 are provided to be in contact with a component connected with the
rotation center screw 11 of theslide mechanism 10, for example, in a case where the inclination adjustment knobs 13 are a direct-acting method, a user grabs one of or both of the knobs of the inclination adjustment knobs 13 at the right and the left and moves the knobs in the vertical direction, and pushes or pulls the contact portions at the right and the left of the inclination adjustment knobs 13, so that the user can adjust the inclination of the component connected with therotation center screw 11 of theslide mechanism 10 connected with thelenticular lens 5 with respect to therotation center screw 11 serving as the center of rotation.

When the inclination adjustment knobs 13 are of a screw method, the inclination is less likely to deviate from the adjusted state because of the friction of the screw even if the user releases his or her hand from the inclination adjustment knobs 13 after the adjustment of the inclination adjustment knobs 13. - In this case, the position adjustment mechanism of the image display apparatus according to the second embodiment refers to the horizontal adjustment knobs 12 and the inclination adjustment knobs 13.
- Therefore, in the image display apparatus according to the second embodiment, like the first embodiment, when the horizontal adjustment knobs 12 and the inclination adjustment knobs 13 are adjusted, the
